[PATCH] iconv: fix to=utf32 to behave like utf32be (not... ascii?)

Attached, I think it's just a case of a missing case statement.

This is needed or the result can't be read back as utf32 which seems
like an important property.

Subject: [PATCH] iconv: fix conversion to utf32, treat like utf32be

I'm not sure how best to describe current behavior,
we treat to=utf32 somewhat like to=ascii
and the result is not valid UTF32.

This change treats to=utf32 like to=utf32be,
similar to what's done with utf16.
